They've (top exec's) done a poor job of "maximizing shareholder wealth" for the last 5 years, only teachers , toll collectors, and politicians can do a krap job for that long without being fired. If the employees performed at that level they'd be in the street. They're a joke in a fancy suit.
Interestingly, Goldman Sachs, which has been one of those long-term skeptics on BDX, has turned markedly bullish recently in several reports, one after the other. It's clear they think things are changing for the better.
